Nostalrius Begins - Quality wow vanilla realm (1.12)

I've noticed you can't search for items "of X wrath" by name on the AH. It always turns up zero results, even when you're sitting there looking at the item listed. For example, looking at a "Cobalt Ring of Arcane Wrath" then trying to search for it never works unless you get it in a generic list for "Cobalt Ring".
Searching for "wrath" or "arcane" both fail too (with the latter only returning arcane crystals and such). Was this a 1.12 bug or something specific to Nost? It makes it hard to find gear when trying to maximize a particular +damage build.

It's supposed to work like that. Not bugged. You can't search for affixes, just base item names.
